An efficient rhodium-catalyzed synthesis of C2-alkylated NH-free indoles has been achieved from substituted indoles and cyclopropanols. The reaction allows the synthesis of various C2-alkylated products in good to excellent yield. Important features of the method include the use of a N,N-dialkylcarbamoyl group as a traceless directing group, C–H/C–C bond functionalization, good functional group tolerance
已经从取代的吲哚和环丙醇实现了有效的铑催化合成 C2-烷基化的无 NH 吲哚。该反应允许以良好至优异的产率合成各种 C2 烷基化产物。该方法的重要特点包括使用N,N-二烷基氨基甲酰基作为无痕导向基团,C-H/C-C键官能化,良好的官能团耐受性,适用范围广,可合成吡咯并[1,2- a ]吲哚,并鉴定潜在的中间体。
